WHAT ASTER DOES

A full Osmium client for Android.

Aster is designed as its own client experience while staying connected to the Osmium network.

Made for Android

Native interactions, Android notifications, media pickers, background delivery, and a UI designed for phones.

GIFs built in

Search and share KLIPY GIFs without leaving the conversation.

Voice & video

Join calls, manage your audio, share camera video, and stay in the conversation.

Community tools

Manage channels, roles, permissions, moderation, and server settings from your phone.

Built to stay connected

Cached state, persistent drafts, reconnect handling, and background notifications help Aster stay useful on messy mobile networks.
